@Yepa: There are 2-l variations in the spelling of that name. Most of the Alisons/Allisons that I've known in real-life had their names spelled with two l's; so, as a result, that's been my default way to spell that name for my whole life (maybe it's a regional spelling convention endemic to where I grew up but little seen elsewhere). I didn't know that Satin Minions' creator spelled it with one l until it was pointed out in this comment thread. I have since corrected my spelling, thereof, in comments on other SM content that were posted after this comment
